In the
Beginning

The Most Audacious Opening Line in History

The Hebrew word is Bereshit — בְּרֵאשִׁית — and it means "in the beginning." It is the first word of the Bible, the title of the book we call Genesis, and one of the most philosophically loaded statements ever committed to writing. In a single breath, Genesis 1:1 declares that time had a start, that space was created, and that matter came into existence — and that God was the cause of all three.

No hedging. No mythology of eternal cycles. Just a flat declaration: there was a beginning, and someone began it.

A hundred years ago, this was the kind of claim that made scientists roll their eyes. The established consensus in physics held that the universe was eternal and static — it had always existed, it would always exist, and anyone who suggested otherwise was letting religion cloud their judgment. The Bible's opening verse was considered, at best, a charming piece of ancient poetry. At worst, embarrassing superstition.

What has happened since is one of the most remarkable reversals in the history of science. One by one, the discoveries came — and one by one, they pointed toward exactly what Genesis had always claimed: the universe had a beginning.

How Science Discovered What Genesis Already Knew

Einstein's Reluctant Discovery

In 1915, Albert Einstein published his general theory of relativity — arguably the most beautiful and consequential equation in the history of science. Almost immediately, something uncomfortable emerged from the mathematics: the universe could not be static. It was either expanding or contracting. It could not simply sit there forever.

Einstein hated this. The idea of a universe with a beginning felt too much like theology, and he was deeply uncomfortable with its implications. So he added a term to his equations — the cosmological constant — specifically designed to counteract gravity and hold the universe in a permanent, unchanging state. He later called this his "greatest blunder."

Lemaître and the Expanding Universe

In 1927, Georges Lemaître — a Belgian Catholic priest and theoretical physicist — took Einstein's own equations seriously and drew the obvious conclusion: the universe was expanding. Not only that, but if it was expanding now, then it must have been smaller in the past. Trace it back far enough, and you arrive at what Lemaître called the primeval atom — a single point from which everything originated.

Edwin Hubble's Observations Seal It

In 1929, astronomer Edwin Hubble published observations showing that distant galaxies were moving away from us — and the farther away they were, the faster they were receding. This was the observational confirmation Lemaître's theory required. The universe was expanding in every direction, meaning it had once been concentrated in a single point. There had been a beginning.

Even then, resistance continued. Fred Hoyle — who later converted to theism — coined the mocking term "Big Bang" in 1949 as a way of ridiculing the idea. A 1959 Scientific American survey found that two-thirds of American scientists still believed the universe was eternal. The comfort of an infinite cosmos died hard.

The Cosmic Microwave Background: The Case Closes

In 1965, the debate effectively ended. Arno Penzias and Robert Wilson, working at Bell Laboratories, stumbled onto a strange, uniform microwave signal coming from every direction in the sky. No matter where they pointed their antenna — no matter how many times they cleaned the pigeon droppings off the dish — the signal persisted. They had discovered the cosmic microwave background radiation (CMB): the faint thermal afterglow of the Big Bang itself, still permeating all of space nearly 14 billion years later.

The universe had a beginning. Time, space, and matter all came into existence at a single moment in the finite past. This is now the consensus of modern cosmology.

The BGV Theorem: No Escape

In 2003, physicists Arvid Borde, Alan Guth, and Alexander Vilenkin published a landmark paper that closed off the last major escape route. Some cosmologists had hoped that inflationary multiverse models might allow the universe to be eternal in the past — perhaps our universe is just one bubble in an infinite sea of universes stretching back forever.

The BGV Theorem showed this was impossible. Any universe — any collection of universes — that has been expanding on average throughout its history cannot be past-eternal. It must have had a beginning. Alan Guth, who pioneered inflationary theory, put it plainly: the universe can be eternal in the future, but not in the past. Even the multiverse needs a starting point.

Can the Universe Come From Nothing?

If the universe had a beginning, the obvious next question is: what caused it? Some scientists have tried to argue that the universe caused itself — that it literally came from nothing. The most prominent advocate of this position is physicist Lawrence Krauss, who wrote A Universe from Nothing (2012) and delivered a widely-shared lecture making the same argument.

The argument sounds radical and counter-intuitive, which is perhaps why it gets so much attention. But there is a significant problem with it — one that even Krauss himself has acknowledged.

The Problem: Their "Nothing" Isn't Nothing

When physicists say the universe could arise from "nothing," they don't mean absolute nothing — the complete absence of space, time, energy, matter, and physical law. They mean the quantum vacuum: a state in which no particles exist, but which nonetheless contains fluctuating energy fields, obeys quantum mechanical laws, and exists within a spacetime framework.

That is not nothing. That is something — something quite complex, in fact. A universe that arises from the quantum vacuum has not come from nothing; it has come from a prior physical state governed by pre-existing physical laws.

The analogy is exact: imagine I have a $1 million debt and $1 million in assets. My net worth is zero — but that doesn't mean I have "nothing." I have two very real and substantial things that happen to cancel out. The claim that this constitutes "nothing" is a redefinition, not an explanation.

Krauss Concedes the Point

Krauss himself admitted as much. In an interview, he acknowledged that "Nothing isn't nothing anymore in physics" — meaning the "nothing" physicists describe is not the philosophical nothing that the question demands. He is aware that the quantum vacuum is not genuinely nothing, but argues it's the best physics can offer.

Physicists like Sean Carroll are admirably honest about this. When asked why there is quantum physics rather than absolute nothing, Carroll's answer — his own words — was: "Why not?" He acknowledged that no one can explain why physical laws exist rather than nothing, and that the universe and its laws appear to be a package deal that simply is.

The Real Question Physics Cannot Answer

Even if we grant everything Krauss says — that quantum fluctuations in a vacuum can produce a universe — we immediately face a deeper question: where did the quantum vacuum come from? Where did the physical laws governing it come from?

Physicist Alexander Vilenkin, one of the authors of the BGV Theorem, was challenged on exactly this point by philosopher Robert Kuhn. Vilenkin argued that a closed universe with zero net energy could spontaneously arise via quantum tunneling. Kuhn pressed him: "But this isn't really nothing — you have quantum physics, you have general relativity. There are several somethings." Vilenkin conceded: why these laws exist, and who gave them, is "a profound mystery" to which he has no answer.

Physics, by its nature, can only work within a framework of physical laws. It cannot explain the existence of those laws themselves. That question belongs to philosophy — and to theology.

The Kalam Cosmological Argument

One of the oldest and most powerful arguments for the existence of God has been given renewed force by modern cosmology. Philosopher and theologian William Lane Craig, when asked for his single most compelling evidence for God, consistently points to it.

What Must This Cause Be Like?

The logic is airtight. The interesting question is: what can we infer about the nature of this cause?

Outside of space and time. The cause of the universe cannot itself be part of the universe — that would be circular. Since space and time came into existence at the Big Bang, the cause must be timeless and non-spatial.

Immaterial. All matter and energy originated with the universe. The cause, therefore, cannot be made of matter or energy. It must be non-physical in nature.

Uncaused. If the cause of the universe itself had a cause, we simply push the question back a step. The chain of causes must end somewhere — at a cause that itself has no prior cause. The first cause must be self-existent, uncaused.

Extraordinarily powerful. The cause brought into existence all the matter, energy, space, and time in the observable universe — approximately 10⁸⁰ atoms, spread across 93 billion light-years of space. Whatever this cause is, it is not weak.

A timeless, immaterial, uncaused, enormously powerful entity that brought the universe into existence. Theologians have a word for this. They have always had a word for this.

The Precision of the Beginning

Even granting that the universe had a cause, one might still argue for a purely natural one — some spontaneous, uncaused physical event that simply happened to produce our universe. But this position runs into a second, devastating problem: the initial conditions of the universe were not merely present. They were precise to a degree that staggers the imagination.

The Second Law and the Problem It Creates

The second law of thermodynamics tells us that entropy — disorder — always increases over time in a closed system. This means that the universe was more ordered in the past than it is today. As we trace the universe backward toward the Big Bang, we find it becoming more and more ordered, more and more precisely structured.

This creates a paradox for naturalistic accounts of the origin. A natural explosion produces disorder — that is literally what explosions do. But the Big Bang produced a universe of breathtaking order: precise physical constants, finely calibrated forces, the exact conditions necessary for matter to form, for stars to burn, for planets to exist, for chemistry to produce life.

Penrose's Number

Oxford mathematical physicist Roger Penrose calculated the probability that the universe's initial conditions — its extraordinarily low entropy at the moment of the Big Bang — could have arisen by chance. The result is one part in 10^(10^123).

To appreciate how large this number is: the total number of atoms in the observable universe is approximately 10^80. The number of seconds since the Big Bang is roughly 10^17. The number Penrose calculated has more zeros in its exponent alone than there are atoms in the universe. It is a number that physicists describe as functionally impossible.

Penrose concluded that the ordered beginning of our universe cannot be explained by any natural random process. It requires an explanation of a different kind entirely.

Even Albert Einstein, who resisted theism for most of his life, could not ignore what he saw. Confronted with the ordered complexity of the cosmos, he wrote of a conviction that a "superior mind" was revealed in the structure of the universe — a universe too ordered, too precise, too beautiful to be a cosmic accident.

What Genesis Knew All Along

Let us take stock of where the evidence leads.

Science has established that the universe had a beginning — that time, space, and matter came into existence at a finite moment in the past. The BGV Theorem closes off the possibility of an eternal past even for multiverse models.

Attempts to explain this beginning as arising from "nothing" collapse under philosophical scrutiny: the quantum vacuum that physicists invoke is not nothing, and even if it were, the existence of the physical laws that govern it remains entirely unexplained.

The Kalam Cosmological Argument presents a logically valid case that the universe has a cause — and that cause must be timeless, immaterial, uncaused, and extraordinarily powerful.

The fine-tuning of the universe's initial conditions — Penrose's 1 in 10^(10^123) — points not merely to a cause, but to an intentional cause. A cause that chose these initial conditions from among an unimaginable range of alternatives.

The Kalam argument does not prove specifically the God of the Bible. What it proves — rigorously, from scientific premises — is that atheism is not the rational default. A creator exists. This creator is personal, powerful, and purposeful.

The Bible begins: Bereshit bara Elohim et hashamayim ve'et ha'aretz. "In the beginning, God created the heavens and the earth." Written millennia before modern cosmology. Consistent with everything modern cosmology has discovered. And beginning with the one word — in the beginning — that science spent a century trying to disprove, and ultimately confirmed.

The heavens declare the glory of God. The data are just catching up.
